Phytoplankton and Periphyton
Most studies of Amazonian algae concentrate on phytoplankton. Taxonomy and aspects of community structure are discussed by Grönblad (1945); Förster (1969, 1974); Martins (1980); Scott et al. (1965); Uherkovich (1981); Uherkovich and Schmidt (1974); Uherkovich and Rai (1979); Thomasson (1971), and many others. In 1973 Schmidt published the first comprehensive study on primary production of phytoplankton in a várzea lake. In the following years many researchers focussed on the subject and primary production of phytoplankton in central Amazonian floodplain lakes became rather well known (Schmidt 1976; Fisher 1979; Fisher and Parsley 1979; Forsberg 1984; Rai and Hill 1984; Forsberg et al. 1991; Rodrigues 1994; and many others).
